BACK-FILLING MATERIAL FOR FIXING INNER LINING OF PIPE, AND APPLICATION METHOD OF BACK-FILLING MATERIAL FOR FIXING INNER LINING OF PIPE
To provide a back-filling material for fixing an inner lining of a pipe, excellent in miscibility with a main material liquid (liquid A) and a hardening material liquid (liquid B), and exhibiting little viscosity increase of the main material liquid (liquid A) resulting from the passage of time.SOLUTION: A cement based composition constituting a back-filling material for fixing an inner lining of a pipe, comprises a mixture of a main material liquid (liquid A) comprising hydraulic cement, kneading water, and a specific dispersant, and a hardening material liquid (liquid B) comprising alumina cement, anhydrous gypsum and kneading water.SELECTED DRAWING: None
【課題】管内張りの裏込め材において、主材液（Ａ液）と硬化材液（Ｂ液）との混合性に優れ、主材液（Ａ液）の経時による粘度上昇も小さい管内張りの裏込め材を提供する。【解決手段】管内張りの裏込め材を構成するセメント系組成物であって、水硬性セメント、混練水及び特定の分散剤が含まれる主材液（Ａ液）と、アルミナセメント、無水石膏及び混練水を含む硬化材液（Ｂ液）とが配合されてなる。【選択図】なし
